一 中国在全球板块运动的各发展阶段中所处的构造位置和环境,从“前文”中已可大致知晓。在前寒武纪早中期它是联合古陆核的一部分,晚期可能开始分裂,北部与中西伯利亚占陆核,西北部与欧洲古陆核脱离,其间有卡腊山、莫印特、切利诺格勒、乌兰巴托、牡丹江等花彩岛式的古陆块,南部可能从中国古陆核上分裂出去了掸一丹那沙林和昆嵩小陆块。这时中国古陆西北部与西西伯利亚海相接,北邻亚洲海,东濒古太平洋,西南被古地中海包围。其后主要经历了两个重要的发展阶段:
The location and environment in which China is located in various stages of the development of the global plate movement are generally known from the “Preface”. Early in the Precambrian it was part of a united ancient land core that may begin to divide in the late stage, with northern and central Siberia accounting for the continental nucleus, northwestern Europe separated from the ancient continental nucleus, with Mount Kalashan, Mojind, Ngale, Ulan Bator, Mudanjiang and other Hua Wa Island type of ancient landmass, the southern part of the ancient Chinese mainland may have split Shan Shan Sarin and Kun Song small land block. At this time, the northwestern part of China ancient land is connected with the sea in the West Siberian Sea, with the Asian Sea in the north and the eastern Pacific in the east, and the ancient Mediterranean Sea in the southwest. After that, it mainly experienced two important stages of development:
